An analysis of lung cancer mortality in a cohort of 1,669 Mayak workers who started their employment in the plutonium and reprocessing plants between 1948 and 1958 has been carried out in terms of a relative risk model. Particular emphasis has been given to a discrimination of the effects of external gamma-ray exposure and internal alpha-particle exposure(More)
From 1946 to 1990 extensive uranium mining was conducted in the southern parts of the former German Democratic Republic. The overall workforce included several 100,000 individuals. A cohort of 59,001 former male employees of the Wismut Company was established, forming a large retrospective uranium miners' cohort for the time period 1946-1998. Mean duration(More)
An increased risk of cardiovascular diseases after exposure to low doses of ionizing radiation has been suggested among the atomic bomb survivors. Few and inconclusive results on this issue are available from miner studies. A positive correlation between coronary heart disease mortality and radon exposure has been reported in the Newfoundland fluorspar(More)
A new analysis of lung cancer mortality in a cohort of male Mayak workers who started their employment in the plutonium and reprocessing plants between 1948 and 1958 has been carried out in terms of a relative risk model. The follow-up has been extended until 1999, moreover a new dosimetry system (DOSES2000) has been established. Particular emphasis has(More)
Lung cancer mortality was analyzed among 4279 nuclear workers of the Mayak facilities in the former Soviet Union, who were exposed to chronic irradiation both externally and internally from incorporated plutonium. The analysis was carried out in terms of a relative risk model. It was shown that an earlier estimate of the excess relative risk for lung(More)
Mainly between 1945 and 1955, several thousand German patients with ankylosing spondylitis, tuberculosis, or--in a few cases--other diseases received multiple injections of the short-lived alpha-particle emitter radium-224. In the early 1950s, the follow-up of 899 patients was initiated, and the study has continued since then. It includes most of the(More)
One of the features of high LET alpha-ray exposure due to radon inhalation is the well-known inverse dose-rate effect. The longer a given dose is delivered to the lung, the higher is its carcinogenic effect. This introduces the problem of risk extrapolation from high levels of radon exposure typical for uranium miners, down to low levels of radon exposure(More)
The risk of radiation-induced cancer is assessed through the follow-up of large cohorts, such as atomic bomb survivors or underground miners who have been occupationally exposed to radon and its decay products. The models relate to the dose, age and time dependence of the excess tumour rates, and they contain parameters that are estimated in terms of(More)
